gmp library

how can i use gmp library for large numbers in c++ ?
I have written the code , but its giving compilation error on codechef.
But it works in some online IDEs.
Please suggest a way of using gmp library here.

You should know that it is not possible to include libaries from outside the c++ standard.
There is no way to solve your problem.
